The next release of the Firefox 1.5 Beta (formerly released as Deer Park) is now available. This is release candidate 3, meaning it is largely finished, and is undergoing compatibility testing in a wide of environment as possible. That is, of course, where users come in. This is beta software, with no actual user end support yet, but if you want the latest most blistering features and like participating in betas, it is of course free to grab. I've been using it for a while and it seems quite robust, giving Firefox a more polished feel that seems more stable. One thing a lot of people have wanted for a long time is drag and drop re-ordering of tabs, which FF now has available. Release notes are available on Mozilla's site.
